AHU cleaning in Great Maplestead
Where a building in Great Maplestead has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you have dirty coils holding back the airflow and filters that are clogged or overdue, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Honest limits
A few issues sit outside what this work can do:
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly.
What the work covers
- Filter sections
- Internal panels
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Dampers and louvres
Between visits
So the system stays in good health:
- Stick to the filter change plan
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
- Flag stale or damp smells in the supply air
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Why it’s worth doing now in Great Maplestead
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Rural sites can’t always move to another kitchen or room when something fails.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or send us an email, and we’ll talk you through it.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

What should I send you?

Where does the waste go?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
How long does it take to clean an air handling unit?
It takes half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. Somewhere like Great Maplestead, lanes, gates and parking are worth mentioning in advance.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive

Signs you need AHU cleaning in Great Maplestead
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Great Maplestead, that is air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
- Air handling units with blocked filters
Classrooms and halls at schools such as St Giles' Church of England Primary School are easiest to work in when pupils are away.
Before booking anyone
- How VAT is shown on the quote
- Whether the figure could change on the day
- Whether a written report and pictures are included
- Whether they’re fully insured
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
